Flex-Pro A3 Series Peristaltic Pump for high pressure and high accuracy applications.
Spec the A3 in your next job... Engineering Spec Sheet DOC
Benefits of a Peristaltic Pump:
Peristaltic pump design does not have valves that can clog requiring maintenance.
Self priming - even against maximum line pressure. By-pass valves are not required.
Cannot vapor lock or lose prime.
Communication & Interface:
SCADA Inputs include: 4-20mA, 0-10Vdc, and Pulse inputs for remote external
speed control and 0-30 VDC / contact closure remote start/stop.
Shown with optional
Operator friendly digital touch pad with menu driven software.
VGA Graphic multi-color backlit LCD displays remote/local control status, motor speed,
output rate, input signal values, service and alarm status.
Outputs include: Scalable 4-20mA or pulse, one 250V/6A relay and three 115V/1A contact closures
assignable to monitor up to 17 different pump functions including TFD, FVS, remote/local
control setting, motor on, fault, current operating mode, and others.
Compatible with Blue-White's output Flow Verification Sensor (FVS) system.
Superior Engineered Design:
Two CNC precision machined squeeze rollers and two alignment rollers for optimum squeeze,
unparalleled accuracy, and tube life.
Heavy duty rotor - single piece plastic rotor means no flexing and increased accuracy with
no metal springs or hinges to corrode.
No maintenance brushless variable speed motor.
Specially engineered tubing for long life at high pressures. Meets FDA 21 CFR requirements
for food contact applications.
Patented Tube Failure Detection (TFD) system. Senses tube failure by detecting
chemical in the pump head. No false triggering.
Patented Component Control System.
Eliminates Need for External PLC
A method used to control two or more positive displacement pumps in a system. The Component Control System ensures that two or more positive displacement pumps, operating in a system together, will run only if all pumps in the system are running.
This can reduce costs by eliminating the need for separate pump controllers for each unit. This feature will be particularly important when failure of one pump to meter chemical could have a damaging effect on the entire process, for example; when pumping two or more chemicals into a system using multiple pumps, particularly when two or more chemicals rely on one-another to achieve desired results (i.e. Chemical reaction).
With the patented Component Control System, if one pump should stop running for any reason, all pumps will stop running.
Patented feature to extended tube life.
The Method comprises switching the inlet and outlet connections of the peristaltic pump, and reversing the rotational direction of the roller assembly, thereby moving the wear point of the tube which results in approximately double the useful life of the tubing.
The patent includes: Identify usage information of the tubing of the peristaltic pump, and ability to stop the pump automatically after a certain number of rotor revolutions.
Implementation of the method discussed above can also result in cost and time savings. Clearly, by extending the life of the tubing, replacement costs are substantially decreased. However, implementing such a method can also save production and replacement time that would otherwise be sacrificed in maintaining the system. Included on all Flex-Pro pumps.
Patented Safety Switch.
Maintenance Mode Operating Feature
Protects the pump operator when performing maintenance to the pump head, such as cleaning the pump tube. The switch stops the pump when front cover is removed. The pump will only operate in maintenance mode while the front cover is removed, helping to ensure operator safety. Included on all Flex-Pro pumps.
